I'm trying to figure out how to initialize a multi-dimentional array
with a struct. I thought it would be straight forward, but i'm running
into problems. I'm using nested for loops, and just setting the current
index to a blank version of my struct but that gives me this error:
"Error: no [] operator overload for type Node". I didn't know I needed
to overload that operator, usually didn't need to in C++ as far as I
remember.
struct Node
{
bool walkable;
vect2 position;
int xIndex, yIndex;
Node*[4] connections;
}
void InitializePathGraph()
{
for( int x = 0; x < mapWidth; x++ )
{
for( int y = 0; y < mapHeight; y++ )
{
Node node;
PathGraph[x][y] = node;// ERROR
}
}
}

Do you want to initialize with the default value of Node? Then it is as
easy as the following:
import std.stdio;
struct Node
{}
void main()
{
Node[2][3] a; // fixed-length of fixed-length
Node[][] b = new Node[][](2, 3); // slice of slice
writeln(a);
writeln(b);
}
The output:
[[Node(), Node()], [Node(), Node()], [Node(), Node()]]
[[Node(), Node(), Node()], [Node(), Node(), Node()]]
Please note the different meanings of 2 and 3 for the fixed-length array
and the new expression: lines and rows are swapped!
